STRINGSTRING
STRING protein interaction network
Nodes:
Network nodes represent proteins
splice isoforms or post-translational modifications are collapsed, i.e. each node represents all the proteins produced by a single, protein-coding gene locus.
Node Color
colored nodes:
query proteins and first shell of interactors
white nodes:
second shell of interactors
Node Content
empty nodes:
proteins of unknown 3D structure
filled nodes:
a 3D structure is known or predicted
Edges:
Edges represent protein-protein associations
associations are meant to be specific and meaningful, i.e. proteins jointly contribute to a shared function; this does not necessarily mean they are physically binding to each other.
Known Interactions
from curated databases
experimentally determined
Predicted Interactions
gene neighborhood
gene fusions
gene co-occurrence
Others
textmining
co-expression
protein homology

rpoHRNA polymerase sigma-32 factor; Sigma factors are initiation factors that promote the attachment of RNA polymerase to specific initiation sites and are then released. This sigma factor is involved in regulation of expression of heat shock genes. (284 aa)    
Predicted Functional Partners:
rpoA
DNA-directed RNA polymerase; DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates.
 
 
 0.968
rpoB
DNA-directed RNA polymerase; DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates.
 
 
 0.953
rpoZ
DNA-directed RNA polymerase; Promotes RNA polymerase assembly. Latches the N- and C- terminal regions of the beta' subunit thereby facilitating its interaction with the beta and alpha subunits.
 
 
 
 0.950
rpoC
DNA-directed RNA polymerase; DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates.
 
 
 0.937
ada
Methylated-DNA--[protein]-cysteine S-methyltransferase (6-O-methylguanine-DNA methyltransferase) (O-6-methylguanine-DNA-alkyltransferase) InterPro: Methylated-DNA--protein-cysteine methyltransferase; High confidence in function and specificity.

dnaJ1
Chaperone protein DnaJ; Participates actively in the response to hyperosmotic and heat shock by preventing the aggregation of stress-denatured proteins and by disaggregating proteins, also in an autonomous, DnaK-independent fashion. Unfolded proteins bind initially to DnaJ; upon interaction with the DnaJ-bound protein, DnaK hydrolyzes its bound ATP, resulting in the formation of a stable complex. GrpE releases ADP from DnaK; ATP binding to DnaK triggers the release of the substrate protein, thus completing the reaction cycle. Several rounds of ATP-dependent interactions between DnaJ, D [...]

nusA
Putative N utilization substance protein A; Participates in both transcription termination and antitermination.
 
 
 0.835
dnaK
Chaperone protein DnaK; Acts as a chaperone; Belongs to the heat shock protein 70 family.
 
 
 0.829
dnaJ2
Putative chaperone protein dnaJ. homology to dnaJ of E. coli of 32% (sprot|DNAJ_ECOLI) Acts as a co-chaperone. Stimulates jointly with grpE the ATPase activity of dnaK (By similarity). Pfam: DnaJ domain, DnaJ central domain (4 repeats), DnaJ Cterminal region no singal peptide no TMHs; Family membership.
   
 
 0.821
hscA
Probable chaperone protein; Chaperone involved in the maturation of iron-sulfur cluster- containing proteins. Has a low intrinsic ATPase activity which is markedly stimulated by HscB.
